Issue
I have a web app written in Java and Spring MVC.
There's a REST web service, when it works I get back the Employee in JSON format.
But where there's an error, I get back a big JSON string that contains an HTML error page that doesn't include my sErrorMsg string (a sample of the error JSON is included below).
QUESTION: How do I get the error response to be a simple JSON string with my error message in it?
@RequestMapping(value = "/json/employee/{employeeId}", method = RequestMethod.GET)
@ResponseBody
public ResponseEntity<Employee> getEmployee(@PathVariable("employeeId") int employeeId) throws Exception {
Employee employee = null;
String sErrorMsg = "";
try {
employee = employeeService.getEmployee(employeeId);
} catch (Exception x) {
sErrorMsg = "Error getting employee; "+x.getMessage();
// UPDATE:
// throw x; <<-- errant line here was causing the problem
//
}
ResponseEntity responseEntity = null;
if (ret != null) {
ResponseEntity responseEntity = ResponseEntity.ok(employee);
} else {
responseEntity = ResponseEntity.badRequest().body(sErrorMsg);
}
return responseEntity;
}
Error JSON ...
{"readyState":4,"responseText":"<!doctype html><html lang=\"en\"><head><title>HTTP Status 500 – Internal Server Error</title><style type=\"text/css\">body {font-family:Tahoma,Arial,sans-serif;} h1, h2, h3, b {color:white;background-color:#525D76;} h1 {font-size:22px;} h2 {font-size:16px;} h3 {font-size:14px;} p {font-size:12px;} a {color:black;} .line /* the rest of the HTML which contains a length Java stack trace ... */ }
Solution
I was causing the problem myself with an errant throw x that was here ...
} catch (Exception x) {
sErrorMsg = "Error getting employee; "+x.getMessage();
throw x; // <<-- errant line here was causing the problem
}
I removed the throw x; and it all works fine.
